Abstract

PURPOSE:To assure safe and easy kitchen work and utilize the space of a kitchen sink effectively by connecting a water cooling tube and a filter with a water supply tube and also connecting the filter and a discharge tube of water and hot water combined tap with a filtrate flow tube. CONSTITUTION:A water cooling tube 2 and a filter 8 are connected with a water supply tube 13, and the filter 8 and a discharge tube of water and hot water combined tap 1 are connected with a filtrate flow tube 18. Thus, hot water mixed by the water and hot water combined tap 1 is discharged out of a discharge tube. Cold water only is flowed from the water cooling tube 2 to the filter 8 and filtered to be discharged out of the discharge tube. It is not necessary to provide anything at the end of a bibcock 5 connected to the discharge tube, and kitchen works can be done easily. By installing the filter 8 between the water cooling tube 2 and hot water tube 3, the space of a sink can be effectively utilized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a water supply filtration device equipped with a filter and a hot/cold water mixing faucet.

BACKGROUND OF THE INVENTION In recent years, water filtration devices that integrate a filter and a hot water mixing faucet have come into use.

Hereinafter, this type of conventional water supply filtration device will be explained with reference to FIG.

In this FIG. 4, 41 is a faucet, and this faucet 41
A waterway switching section 42 is provided at the tip of the waterway switching section 42, and a filter 43 is further provided on this waterway switching section 42.

In the above configuration, by operating the switching knob 44 of the water channel switching section 42, water flowing through the faucet 41 can be supplied by passing through the water channel switching section 42, or can be passed from the water channel switching section 42 through the filter 43. The water is then filtered and returned to the water channel switching section 42 before being supplied with water. Note that the water in the faucet 41 passes through a hot water mixer (not shown).

Problems to be Solved by the Invention However, in the conventional water filtration device described above, the waterway switching section 42 and the filter 43 are disposed at the tip of the faucet 41, which interferes with kitchen tasks such as washing dishes, and prevents the sink from working properly. space could not be used effectively. Also, faucet 4
When the hot water passing through 1 enters the filter 43, there is a drawback that substances adhering to the activated carbon in the filter 43 are spit out.

Means for Solving the Problems In order to solve the above problems, the water supply filtration device of the present invention includes:
The cold water pipe and the filter are connected by a water supply pipe, and the filter and the discharge pipe of the hot water mixing faucet are connected by a filtered water outflow pipe.

Function In the above configuration, hot water mixed by the hot water mixing faucet is discharged from the discharge pipe. Further, only cold water from the cold water pipe flows into the filter, is filtered, and is discharged from the discharge pipe. Moreover, there is no need to provide anything at the tip of the faucet connected to the discharge pipe, making kitchen work easier.

Furthermore, by placing the recognition device between the cold water pipe and the hot water pipe, the space of the sink can be used more effectively.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a hot water mixing faucet, to which a cold water pipe 2 for supplying cold water and a hot water pipe 3 for supplying hot water are connected. Reference numeral 4 denotes a discharge pipe for discharging hot water mixed by the hot water mixing faucet 1, to which a faucet 5 is connected. Reference numeral 6 denotes a switching lever mounting portion provided on the hot water mixing faucet 1, and a switching lever 7 is provided on this switching lever mounting portion 6. By operating this switching lever 7, the amount of cold water supplied from the cold water pipe 2 and the amount of hot water supplied from the hot water pipe 3 are controlled, and the amount of hot water supplied from the hot water mixing faucet 1 to the discharge pipe 4 and the faucet 6 is controlled.
The temperature and amount of hot water discharged through can be controlled.

Of course, by operating the switching lever 7, it is also possible to stop the supply of cold water to the hot water mixing faucet 1, and also to stop the supply of hot water.

Reference numeral 8 denotes a filter, which has a configuration as shown in FIG. In FIG. 3, the filter body 9 and the lid 1o constitute an exterior case of the filter 8. A filtration cartridge 12 filled with a filter medium 11 is housed in the filter main body 9 . Reference numeral 13 denotes a water supply pipe provided in the filter main body 9, which is connected to the cold water pipe 2 via a pipe 14, and guides the cold water in the cold water pipe 2 to the filter main body 9. 16 is a water supply opening/closing valve, and a lever 17 is provided via the lever mounting part 16.
It opens and closes by operating the water supply pipe 13 to control the supply of cold water led through the water supply pipe 13 to the filtration cartridge 12. Reference numeral 18 denotes a filtered water outflow pipe provided on the lid 10, which is connected to the connection part 19 of the discharge pipe 4, and is connected to the filtration cartridge 12.
The filtered water is supplied to the discharge pipe 4.

In the above configuration, when the water supply on/off valve 16 is opened by operating the lever 17, the cold water in the cold water pipe 2 is supplied into the certification application cartridge 12 through the pipe 14, the water supply pipe 13, and the water supply on/off valve 15, and residual chlorine and Iron rust and other odor components are removed, and the filtered water outflow pipe 18, connection WXS1
9 to the discharge pipe 4, and is further discharged from the faucet 6. Therefore, hot water does not flow into the filter 8.

On the other hand, when discharging hot water from the faucet 6, by operating the switching lever 7, the cold water pipe 2 is connected to the hot water mixing faucet 1.
At the same time, cold water is introduced from the hot water pipe 3, and hot water is introduced from the hot water pipe 3, mixed at the hot water mixing faucet 1, and the mixed hot water passes through the discharge pipe 4 and the faucet 5 and is discharged.

Further, since the hot water mixing faucet 1 and the filter 8 are not provided at the tip of the faucet 6, kitchen work can be easily performed.

Furthermore, as illustrated, the filter 8 is disposed between the cold water pipe 2 and the hot water pipe 30, so that the space of the sink can be effectively utilized.

Effects of the Invention As described above, according to the present invention, hot water is not introduced to the filter, the filter is not damaged, and the substances that have been introduced into the filter are not discharged, so it is safe. .

In addition, there is no need to install a hot water mixing faucet or a filter at the tip of the faucet, making kitchen work easier and making effective use of the kitchen sink space.
